The Keystone
 
The Keystone

The keystone is also borrowed from the Little cupboard.
That cupboard, Nina Fletcher Little's cupboard, is from a house in Scotland, Ct.
All of these mouldings are made with period planes that leaves a surface that is beautifully smooth and never needs or needed sanding of any sort. The curved moulding around the door opening is carved, as is the curved arch muntin section on the door.
